This invention relates to a fireplace heater and has for its primary object to provide, in a manner as hereinafter set forth, a heater of such class wherein cold air is drawn into flues to be circulated around the sides and back and over the top of the ireboX and also around and between a pair of smoke flues, thereby utilizing aV maximum area of radiating surfaces for warming the air before the latter is discharged into the room.

A further object of the invention is to provide a heater of the class aforesaid wherein the cold air is drawn into the heater at the sides and adjacent the front thereof, whereby with any cold drafts.

A further object of the invention is to provide a heater as aforesaid which is adapted to prevent any air from passing into the chimney except through the iirebon7 and smoke flues, thereby insuring an effective draft for the proper combustion of the fuel.

further object of the inventionis to provide a heater as aforesaid which is adapted for use in burning either wood or coal.

With the foregoing and other objects-in view, the invention consists o f the novel construction, combination and arrangement of parts as hereinafter more particularly described, and as illustrated in the accompanying drawings wherein is shown a preferred embodiment of my invention, but it is to be understood that such drawings and description are to be taken as illustrative and that the invention is intended to be limited only by the scope of the claims hereunto appended.

In the accompanying drawings in which like numerals fare employed to designate like parts throughout the same: y

Figure 1 is a front elevation of a heater constructed in accordance with this invention.

Figure 2 is a side elevation thereof.

the front of the heater is kept out of contact Figure 3 is a rear elevation thereof. Figure 4 is a sectiontaken onl line 4 4 of Figure 3. l i H Figure 5 is a section takenv on line 5 5 of Figure 3. y n 50 Figure 6 is a section taken on line 6-6 of Figure 3. i

Figure 7 is a transverse vsection of the heater taken at a point indicated by the line 7-1-7 i t of Figure t. A y i y Figure 8 is asimilar view taken a't a point indicated by theline 8-v-8 of Figure 4. n

Figure9 is a detailed view of the air dis,-l tributor in top plan.' n 'y y Figure 10 is a perspective view of the heater showing the front thereof.

Figure 11 is a perspective 4view of the heater showing the back thereof. l

Referring to the drawings in detail, .the ,n numeral l designates a base which is substantially in the form of a frame having an open front. Seated within the base are the lower' edges of a pair of inner side walls 2 andv an inner rear wall 8. Each `side wall 2 is formed with a vertical forward edge 4l and an angular rearward edge consistin' Vof a vertical por-k ion 5, a forwardly anv upwardly inclined portion 6, a vertical portion 7, and afer# wardly and upwardly inclined portion 8.

The rear wall 3 consists of a vertical lower portion 9 and a forwardly and upwardly yin-A clined upper portion 10. The upper portion 10 is disposed at the same angle ofinclination as the rear edge'portion 6 of the side walls 2 and terminates intermediate the upper and lower ends of such edge .portions 6. Merging into the upper edge of the rear wall portion lO is a pair of bottom walls l1 for a pair. of spaced flues 12. The inner walls 13 of the iiues 12 converge and mengeV at 85 their forward edges as indicated at 14. The outer Side Walls 15 of. the fines 12 extend in parallel relation and merge into theinliled rear edge portion 6 of the'side walls 2, The

. flues are formed with a common topwall 16,

the rearward portion 17 of which is bifurcated to conform in contour to the flues 12 and the'forward portion 18 of which extends beyond the forward edges of the flues and merges into a pair of oppositely inclined walls 19 and v20. The walls 19, 18, 3 and 2 provide a firebox, the upper and rearwardv rportion of which opens into the flues 12.

Seated on the base 1 is an air distributor indicated generally by the numeral 21 and formed with a bottom wall 22, a side wall 23, and a top wall 24. The inner edges of the bottom wall 22 and top wall 24'abut against the side walls 2 and rear wall 3 and in connection with the walls 2 and 3 the distributor 21 Aprovides an air-conduit around the lower portion of the irebox. The forward ends vof the distributor are formed with a pair of op# positely extending, hollow members 25 which provide air inlets for the distributor, adjacent the forward-portion of the firebox.

Seated on the base 1 is an outer shell vconportions 31 vand 32.. The intermediate portion33 isy disposed at the'same angle of in-' clinationf asfthe inclined wall 20. The upper edges of the side-walls 26 conform in contour tothe topwall 29 and the rear wall 28 is formed with a pair ofspaced openings in registry with the flues 12. One of such openings is indicated at 34, Figure 4. kThe front walls 27 as well as the forward portions of theside walls` 26 seat on the inlet forming members 25 and the inner edges of the front walls 27 Vmerge into the inner sidewalls 2.

VSeated on the distributor 21 and connecting each adjacent pair of side Walls 2 and 26 isan angular partition 35 which consists of a vertical lower portion 36, a forwardly and upwardly inclined intermediate portion 37, and a vertical upper portion 38 which abuts [against the inner face of the inclinedv portion 33 ofthe top 29., The intermediate portions 37 -of the partitions 35 are disposed at the same Vangle of inclination as the rear edge portions; 6 ofthe side walls 2 andare co-exten- Vsi-ve therewith. The topewall 24 of the distributor 21 is formed with a serrated inner edge 39A inorderthat air may pass from the distributor into the space between the iirebox and outer shell on both sides of the partitions 35. v f .Y

Seated on thefflues12isa pair of spaced partitionsY 40., the upper edges of which abut the horizontal portions 31of the top 29, and

the forward and rearward edges of which respectively abut the inclined wall 2O and the rear wall 28 of the shell. The partitions 40 are formed at their vforward ends with angularly disposed extensions 41, the upper edges of which abut against the portions 33 and 32 of the top 29. The portion 32 of the top 29 is spaced from thc upper edges ofthe front walls 27 and inclined wall 20 andthe spaced extensions 41 provide an outlet 42 at the top of the heater midway between the sides thereof. The extensions 41, in connection with the upper portions of the side walls 2 provide a pair of .outlets 43, one of which is disposed on either side of the outlet 42'. y

The upper portions of the inner side walls 2 and side walls26 of the shell provide a pair of outlets 44 which are disposed directly over the side portions of the distributor 21. The side walls 26 and the portion 32 of the top 29 are provided with a flange 45 which isV adapted to seat against the outerface of the fireplace wall, in order to cut off all draft to vthechimney for the fireplace, except through i the air inlet members 25.

When air enters the distributor 21 through the inlets of the'members 25, a portion thereof passes between the serrations inthe edge 39 of the top wall 24 of the distributor to the vspaces in front of the partition 35 on either side of the firebox. This airis warmed by its contact with the sides of the firebox and is discharged into the room through the cutlets 44. Another portion of the air passes from the distributor through the serrations in the edge 39 into the space between the partitions 35 and comes in contact with the rear wall 3 of the firebox. This air also Ycomesin contact with the walls of the flues 12, a portion thereof passing between the ilues and partitions 40 to be discharged into the room through the outlets 42, and a portion thereof being drawn around the outer side walls 15 and top wall 17 of the Viiues and discharged into theroom through Vthe outlets 43.

It is thought that the many advantages of aheater in accordance with this invention will be readily apparent,.and although the preferred embodiment is as illustrated and described, yet it is to be understood that changes may be made in the details of construction,

`which fall within the scope of the invention as defined inthe appended claims.
